Towing and stuff (yes again....).

You can't tie down tightly by the body, as the tiedowns will tear off ( with normal cars you can pull the tiedown nice and snug and watch the suspension slightly compress... there is no suspension with a dead hydraulic car ... so there is no movement until you pull the tie-down points out of the body).

It's all fun though .... life wasn't supposed to be easy :)

Rear axle tiedown stops it going forward, somewhere on the front axle stops it going backwards.
Tying the wheels down is ideal, but you never, ever, if at all possible, tie down anything above the suspension.

I once austioned off a Falcon for Ford when I was at Brisbane plant.
it was tied down onto a rail wagon with chains and turnbuckles a bit too tight .
So it bent at the firewall so that the front doors were proud of the roof about 5 cms.

That's never going to hurt a gearbox ... Not in the cars I own either way.

I can feel the damn car move back/forward 1/2" when driving in traffic as you stop/start (ok, ok, it's probably only 2mm it moves .. but I can feel it move damn it!). Drives me bloody insane. It's the stretch in the ropes. I think I'll need to upgrade to ratchet tiedowns.....

So the car rocking back and forward on the gears (only one or two teeth taking the hammering) or even worse, an auto taking all that on the locking pawl, won't result in any potential problem?
Stretch in the ropes? Yes, I think you need to upgrade your tiedowns! [bigwhistle]

Never in a million years hurt the gearboxes in my cars. they can handle the shock loading of 200hp being thrown through them by side stepping a clutch. There is no way a car rocking on the high tensile steel gears is going to hurt them.... Well the old Traction Avant ... they have been known to break gearbox casings if you try to roll start them... But that's not a car resting on the gears. That's a shock loading in the opposite direction to normal gearbox rotation.

I don't own any slugomatics... And the only car I own with a "rear axle" as such are the Range Rovers. All others have either trailing arm torsion bar suspension, or trailing arm fully hydraulic suspension. There is no "axle" to tie down. Same deal at the front,.. wishbone independent suspension with either torsion bars or full hydraulics.

I've never heard of any car .. well ever ... get hurt by leaving it in gear :)

Perhaps you should talk to gearbox specialists then... they can recount numerous cases of bearing damage from such behaviour...

Same as using “Angel gear” and coasting down hills... shakes the crap out of gearboxes by leaving shafts slapping around unloaded.

There a splash box in most of the old cars... How many years/hundreds of thousands of kms would you have to let them "rattle" for any damage to be done. It would never happen with negligible movement on a softly sprung car trailer. Maybe if you had it rattling itself to death across from perth on a freight train.

I'm talking a tied down car on a car trailer that also has the handbrake on [bighmmm]
